Probing the baryonic--dark matter connection in galaxy clusters using X-rays with gated recurrent unit neural networks
Asif Iqbal, Subhabrata Majumdar, Weiguang Cui +3
Accurate cluster mass measurements are crucial for cosmology, yet conventional hydrostatic equilibrium (HSE) methods can suffer from systematic biases, particularly in dynamically…
The plethora of diffuse emission in Abell 2034 as revealed by MeerKAT polarization observations
A. Bonafede, M. Balboni, G. W. Pratt +15
We present MeerKAT observations of the galaxy cluster Abell 2034, a massive (M_500=5.21 10^14 solar masses) nearby cluster in a merging state. Previous observations at 144 MHz have…
Radio Halos in Galaxy Clusters as unveiled by the SKA telescope
R. Cassano, G. Di Gennaro, V. Cuciti +24
Giant radio halos (RHs) are diffuse, Mpc-scale synchrotron sources observed in a growing fraction of galaxy clusters. They trace relativistic particles and magnetic fields in the i…

Euclid Collaboration, R. Ingrao, M. Costanzi +280
We present \texttt{CosmoPostProcess}, a simulation-based forward-modelling algorithm calibrated to reproduce Euclid optical cluster observables. Its main deliverable is a correctio…
Multi-scale weak lensing detection of galaxy clusters with source redshift tomography
L. Chappuis, S. Pires, G. W. Pratt +4
Recently, a number of methods have emerged to detect galaxy clusters solely through their weak lensing signal. Using the recently-introduced wavelet multi-scale detection method, w…
CHEX-MATE: Are we getting cluster thermodynamics right?
R. Seppi, D. Eckert, E. Rasia +19
Galaxy clusters offer powerful insights into the large-scale structure of the Universe and the physics of baryons in hot state. Their scientific exploitation, however, hinges on ou…
